Incident message Description Type
Fault current too
high
The fault current that flows from the plus or minus input via
the solar modules, exceeds the permissible value. Pursuant to
statutory regulations, the inverter switches off automatically as
long as this fault is pending.
u
Notify your installer.
Faulty reading of
country setting
The inverter could not correctly read out the country setting
from the memory.
u
Notify your installer.
Fan defective
The internal fan of the inverter is defective. It is possible that
the inverter injects into the grid with reduced capacity.
u
Notify your installer.
Grid frequency
too high for
switch-on
After switch-off, the inverter cannot inject again because the
grid voltage exceeds the legally prescribed switch-on value.
u
Contact your installer if this error occurs frequently.
Grid frequency
too low for
switch-on
After switch-off, the inverter cannot inject again because the
grid voltage is below the legally prescribed switch-on value.
u
Contact your installer if this error occurs frequently.
Grid frequency
too high
The grid frequency applied on the inverter exceeds the
permissible value. Pursuant to statutory regulations, the
inverter switches off automatically as long as this fault is
pending.
u
Contact your installer if this error occurs frequently.
Grid frequency
too low
The grid frequency applied on the inverter is below the
permissible value. Pursuant to statutory regulations, the
inverter switches off automatically as long as this fault is
pending.
u
Contact your installer if this error occurs frequently.
Grid relay
defective
The inverter has detected that a grid relay is defective; for this
reason, it is not injecting into the grid.
u
Notify your installer.
Grid voltage too
low for switch-on
After switch-off, the inverter cannot inject again because the
grid voltage is below the legally prescribed switch-on value.
u
Contact your installer if this error occurs frequently.
Grid voltage Æ
too high
The output voltage averaged over the legally prescribed time
period exceeds the permissible tolerance range. The inverter
switches off automatically as long as this fault is pending.
u
Contact your installer if this error occurs frequently.
Grid voltage Æ
too low
The output voltage averaged over the legally prescribed time
period is below the permissible tolerance range. The inverter
switches off automatically as long as this fault is pending.
u
Contact your installer if this error occurs frequently.
